If your city is a clogged, smoggy, water-shortaged mess today, what do you think it's going to be like in another few decades?

10.) Pittsburgh

One of the most livable cities in the country, with smart growth, lots of universities and a diverse economy. It may have been a symbol of America's lost industry, but it looks like it's making a comeback.

4.) Chongqing

In the mid-2000s, this somewhat remote city was the fastest growing in the world, booming up to an incredible 28 million residents in its metro area. It turns out that all that growth was backed by corruption and debt, but the city still has enough money to stay great. It's on the Yangtze, sprawl is checked by nearby mountains, and did I mention they have tons and tons of money?

3.) Shanghai

While Chongqing still represents something of potential, Shanghai is more realized. Its infrastructure in particular, as reader stigalicious explains, is noteworthy.

I go to Shanghai quite a bit for business. Their infrastructure is amazing. They have the largest metro system in the world (over 330 miles of track), elevated highways are well-designed and are everywhere, there's more than enough water to go around, and the Chinese are very good at building upwards instead of outwards. You can take a 350kph train from Shanghai to Beijing in under 5 hour and it will cost you under $50 to do so in a comfortable, quiet, and not overly-crowded train car. There's so much more real estate that has been built than there is demand, so housing prices will continue to drop for the forseeable future.

There are two VERY large airports that service Shanghai, and as long as their stupid military stops randomly closing off the airspace every morning for "drills," air is another excellent way to travel.

Pollution and non-potable water are Shanghai's (and most other Chinese city's) biggest problems. Water is non-potable, so everyone boils their water before drinking. Tea is obviously very popular. Pollution has gotten a bit better this year, but there's still a very long way to go. The last time I was there a couple months ago was the cleanest I've ever seen: BLUE SKIES!!!

2.) Calgary

The tar sands are making Alberta rich, and while Calgary might not be the nicest city, it is prepared. JohnnyWasASchoolBoy explains.

As much as I don't like the city I'll nominate Calgary Alberta. It has regularly upgraded and expanded its airport. Their major arterial routes (Stony Trail, Shaganappi Trail... really all the roads with "Trail" in the name) have been upgraded or are in the process of being upgraded. The City is encouraging major infill in its downtown and beltline - lots of people living in denser surroundings, using fewer cars, being more walkable, and placing fewer demands on hard-surface infrastructure. There has been a serious investment in both Arts and Culture, and sports & recreation facilities. They are taking pains to ensure that green space is preserved where they can.
